Abstract

Face recognition in pictures or videos is trending research area in the field of biometric system and application. In so many it is very easy to see the video surveillance cameras and camcorders for security and safety. It is very widespread that it has been recognized that face recognition plays an important role in the monitoring system as it does not require the subject of cooperation. The real benefits of face-to-face recognition of other biometric technologies are unique and responsive. Just like humans, the face is a very dynamic aspect of the object, making face detection a problem of computer vision. In this sense, identifying precision and speed is a major issue. The purpose of this paper is to evaluate the detection of different faces. The identification method provides a complete solution for recognizing front images and better recognition, a better response rate is the first step in video surveillance............

Keywords: Face Recognition, Biometric Identification, PCA, Mahalanobis Distance, AT & T Database, MATLAB.

Abstract

This paper includes modal analysis and harmonic analysis studies for a bolted joint test rig. Machinery vibration problems, e.g. bolt loosening, may get more severe if the operational frequency of the systems matches with any of the natural frequencies of the system. Such problems can be controlled by carrying out modal and harmonic analysis of the system. The test rig considered in this work is a multibody system (MBS) and includes eight components in it. Various components of the system have been modelled in the CAD environment. These components are then assembled to get the overall CAD model of the experimental bolted joint test rig. Modal analysis of flexible components of the system has been carried out. This is followed by modal and harmonic analysis of the CAD model of the experimental test rig. Modal analysis helps in identifying resonance regions. Such primary analysis of system plays important role in studying loosening of bolted joints as well as in finding out fatigue strength of the dynamic systems.

Keywords: Bolted Joints, Natural Frequency, Modal Analysis, Harmonic Analysis.

Abstract

EEG signals are generally measured on multiple locations for Brain Computer Interface (BCI) application as well as other modalities. This high number of channel count increases complexity of algorithm additionally gives discomfort to patient. In order to resolve both problems we have proposed an approach based on higher order statistics like kurtosis, Skewness and moment. Based on them we find channels of highest deviation during onset of activity. The selected channels classification accuracy compared with Linear Discriminant Analysis, Artificial Neural Network and Support Vector Machine on publically available database on physionet website.

Keywords: EEG, Brain Computer Interface, Channel Selection, kurtosis, Skewness, Moment, Linear Discriminant Analysis, Support Vector Machine, Artificial Neural Network, Statistical Features.

Abstract

Nitrogen doped titanium dioxide (NTiO2) thin films were deposited on glass substrates using dc reactive magnetron sputtering technique and their composition, crystalline structure, surface morphology and optical properties were studied as a function of substrate bias voltage. The films exhibited amorphous structure irrespective of the substrate bias voltage. From the SEM images, grain size of the films increases with increasing the substrate bias voltage. The optical band gap of the films was narrowing from 3.07 to 3.02 eV with increasing the substrate bias voltage. The wettability of the films increases with substrate bias voltage.

Keywords: Titanium dioxide, Nitrogen doped, Thin films, Sputtering, Bias voltage

Abstract

In the present study, thermal analysis of a linear parabolic solar collector has been studied by using circular and semicircularabsorbertube. Computational fluid dynamics analysis has been carried out by using non uniform heat flux distributions on the surface of the absorber tube. The non uniform heat flux distribution on the absorber tube is calculated by using Monte Carlo ray tracing method in the SolTrace software. The results are presented for the conventionalabsorber tube receiver and semicircularabsorber tube receiver, for the range of inlet temperature 300K to 650K and Reynolds numbers 0.25x105 to 2.82 x105. The maximum gain in the collector efficiency of the parabolic trough collector is found to be 5% at the Reynolds number equal to 25000.
